No support for WBFS, I recommend FAT32. Also, the author says CleanRip has the possibility to corrupt any other data on the storage device, so I recommend an empty FAT32 storage device like a USB stick or SD card. Gamecube games cannot be played from a usb loader, you must play GC games from disc, I'm not sure about usb loader gx, maybe it will load a retail GC disc.
